Abstract

The research has been devoted to benefits for heterojunction silicon PV panels application evaluation. Evaluation has been conducted through numerical simulation and field tests in Moscow conditions. During simulation PV array year energy yields for HJT monocrystalline Si panels have been derived for 2013–2018 years using NASA Power initial satellite data on solar radiation daily sums. Experimental investigation has been realized through multicrystalline and HJT panel comparative test using test bed, simulating small off-grid power unit. Specific energy yield of panel (ratio of energy yield for given period of time to the panel peak power) has been chosen as a criterion for panels operation comparison in both cases. The research novelty is concerned with attempt to estimate additional energy, produced due to amorphous silicon layer presence by means of field tests in different weather conditions. Calculation showed no benefits for HJT PV panels. Experimental research showed that up to 5–6 kWh/m²/day solar radiation sum value HJT panel provides 1–20% power output gain relatively multicrystalline panel with maximum gain of 14–16% in range of 2–2.5 kWh/m²/day solar radiation sum values.

本征薄层异质结光伏电池板运行——数值模拟和莫斯科户外测试

摘要

该研究致力于异质结硅光伏电池板应用效益评估。通过数值模拟和莫斯科条件下的现场测试进行了评估。在模拟光伏阵列年期间，使用 NASA Power 每日太阳辐射总量的初始卫星数据得出了 2013-2018 年异质结单晶硅电池板的能源产量。利用试验台模拟小型离网机组，通过多晶硅和异质结电池板的对比测试，实现了实验研究。面板的比能量产量（给定时间段内的能量产量与面板峰值功率的比率）已被选择作为两种情况下面板操作比较的标准。这项研究的新颖之处在于尝试通过不同天气条件下的现场测试来估计由于非晶硅层的存在而产生的额外能量。计算表明异质结光伏电池板没有任何好处。实验研究表明，高达5-6 kWh/m ² /天的太阳辐射总和值异质结电池板可提供1-20%的功率输出增益，相对多晶电池板而言，在2-2.5 kWh/m 2 范围内最大增益为14-16 ^% /天太阳辐射总和值。
